使用Buildozer构建Kivy安卓应用时出现输出错误

Hey there! Let’s work through this frustrating build issue you’re hitting. Reinstalling Buildozer and Kivy is a good first step, but these types of errors often stem from missing system dependencies, misconfigured Buildozer settings, or version mismatches in the Android SDK/NDK. Here’s a step-by-step breakdown of fixes to try:

1. Fix Buildozer Configuration (buildozer.spec) #

Your buildozer.spec file is likely missing or using incompatible settings. Update these key sections:

• Set a compatible Python version (Linux Mint 19’s default Python 3.6 works well with Buildozer):

  python.version = 3.6
  

• Specify a stable Kivy version to avoid compatibility gaps:

  requirements = kivy==2.1.0
  

• Force a compatible Android NDK/SDK version (older versions often resolve build conflicts):

  android.ndk = 25b
  android.sdk = 33
  

2. Install Critical System Dependencies #

Linux Mint 19 (based on Ubuntu 18.04) requires several system packages that Buildozer relies on. Run this command to install them:

sudo apt-get update && sudo apt-get install -y git zip unzip openjdk-8-jdk python3-pip autoconf libtool pkg-config zlib1g-dev libncurses5-dev libncursesw5-dev libtinfo5 cmake libffi-dev libssl-dev

Important: Ensure you’re using OpenJDK 8—newer Java versions are not fully compatible with the Android build tools used by Buildozer.

3. Clear Buildozer Cache & Old Build Files #

Stale cache or corrupted build artifacts often cause repeat failures. Clean everything up with these steps:

• Run the official clean command:

  buildozer android clean
  

• Delete the hidden .buildozer directory (this stores SDK/NDK and build intermediates):

  rm -rf .buildozer
  

• Remove old APK files from the bin directory if they exist:

  rm -rf bin/
  

4. Use a Virtual Environment for Isolation #

System-wide Python package conflicts can break builds. Create a fresh virtual environment to isolate your Kivy/Buildozer setup:

1. Create and activate the environment:

   python3 -m venv kivy_build_env
   source kivy_build_env/bin/activate
   

2. Install stable versions of Buildozer and Kivy:

   pip install buildozer==1.4.0 kivy==2.1.0
   

5. Set Correct Environment Variables #

Ensure Buildozer can find Java and other tools by setting these variables:

• Export JAVA_HOME temporarily:

  export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
  

• Make this permanent by adding it to your ~/.bashrc:

  echo "export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64" >> ~/.bashrc
  source ~/.bashrc
  

6. Get Verbose Logs for Further Debugging #

If the issue persists, run the build with verbose logging to pinpoint the exact failure point:

buildozer android debug -v

Look for error messages related to missing libraries, failed downloads, or version mismatches—these will give you more specific clues to resolve the problem.
